Noise-resilient sequential circuits for generating quantum order
Konstantin Gattinger, Julian Boesl, Max McGinley +2
Sequential circuits provide an optimal linear-depth route to unitarily preparing long-range ordered quantum states, but circuit-level noise can be far more damaging than noise appl…
Entanglement Pattern Transition of Quantum States from Directed Percolation
Julian Boesl, Frank Pollmann, Michael Knap
Changes in the entanglement structure and critical phenomena are hallmarks of quantum phase transitions. Here, we discuss how they appear in transitions between classes of states w…
Quantum trajectory simulation of two-dimensional non-equilibrium steady states with a trapped ion quantum processor
Anna Dalmasso, Arash Jafarizadeh, Julian Boesl +8
Digital quantum computers offer a promising route for studying complex many-body systems that are otherwise inaccessible by their classical counterparts. Capabilities including mid…
Skeleton of isometric Tensor Network States for Abelian String-Net Models
Julian Boesl, Yu-Jie Liu, Frank Pollmann +1
We construct parametrized isometric tensor network states -- referred to as skeletons -- that allow us to explore phases of abelian topological order and can be efficiently impleme…
Quantum Phase Transitions between Symmetry-Enriched Fracton Phases
Julian Boesl, Yu-Jie Liu, Wen-Tao Xu +2
Topologically ordered phases exhibit further complexity in the presence of global symmetries: Their anyonic excitations may exhibit different transformation patterns under these sy…
Deconfinement Dynamics of Fractons in Tilted Bose-Hubbard Chains
Julian Boesl, Philip Zechmann, Johannes Feldmeier +1
Fractonic constraints can lead to exotic properties of quantum many-body systems. Here, we investigate the dynamics of fracton excitations on top of the ground states of a one-dime…
